The story i read was, what was the name of the driver and did it run on Linux…
There could be infinite answers but choose one
On iPad I use ProCreate (I bought it) - IMHO it’s vastly better than Krita… Krita just has too many options…
I also use AutoDesk Sketchbook on iPad (and Android - but there’s no Android version of ProCreate)…
Here’s something I did in Procreate 8 years ago (most of the ink lines were done in the late 1980’s on paper):
I guess I should use it more - seeing’s how I paid for it…
Your artwork leaves me for dead.
Nice image but could not ride it !
Well, she said Procreate has too few options… 
Fewer than Krita… When you want to create stuff - you don’t want a UI getting in the way ?(my experience of Krita, and also GIMP and Photoshop - too many options choices)…
Not “too few” options - but just enough - thus adhering to the KISS principle <3
Autodesk Sketchbook is even more barebones (sidenote : Autodesk Sketchbook was originally a Silicon Graphics app from when SGI owned Alias Wavefront released a painting app for UNIX (IRIX) and Windows)…
Kinda odd - I have no idea if it’s age - or a severe head injury I copped in early 2017 - but I have no ability to “draw stuff” from scratch… All I seem to be able to do these days is take stuff I made decades ago and edit / paint / colour in…
